Blake allegedly feels he is entitled to the large sum as he says that he inspired most of Amy’s 2006 LP Back To Black.

Winehouse, who married Fielder Civil in May 2007 reportedly wrote the hit album after her first parting with Blake, where he allegedly cheated on the Camden star with his ex-girlfriend.

A source has claimed: "Amy did write 'Back to Black' when Blake left her, but why on earth should he be getting a dime for making her feel so bad? She was at her lowest ebb when she wrote that album.”

They continued: “It's like saying that the man who writes a book about his murdered wife should give the murderer some of the profits. It's an absolutely ridiculous request."

The Rehab singer, who has recently returned to London after a stint in St. Lucia is said to be furious by her ex hubby’s claim and does not want to negotiate the payment.

A source reportedly told the News of the World: "Amy's distraught because she doesn't think Blake will go quietly. Blake's family don't want him to ask for money but he hasn't given up on a hefty pay day."

"Amy is furious and doesn't want to negotiate. But she's happy for his outrageous demands to be made public because she wants to show him up."
